Defects Analysis and Troubleshooting of Moulded Parts

Date : 25 to 26 February, 2021

Time : 1400 Hrs to 1700 Hrs

Introduction

Injection moulded parts are widely used in automobiles, consumer goods, medical parts, aircraft interiors and across many more types of products. Parts that may vary in shape, size and complexity are manufactured using Injection moulding process in a moulding machine. 

The process involves injection of plastic material into a cavity, where the material cools and hardens as per the configuration of the cavity. Injection moulding can be performed with a host of materials like elastomers, thermoplastic and thermosetting polymers. Moulds are made by a mould-maker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part.

Injection moulding process poses many challenges, which may lead to defects in the final parts. In order to successfully manufacture a moulded part, it is important to understand the possible defects, get an understanding of the parameters that control the moulding process, which could be incorporated at the mould design stage itself.

Keeping this in mind, IMTMA is organizing a two day online training program on Defects analysis and Troubleshooting of Moulded parts.
